Six prodigies attend Kanezono Academy of Music, each with a mysterious past and a “color” tied to their soul’s melody. The story follows Ren Hayami, a withdrawn violinist who hasn’t played since his sister’s suicide. On his first day, he hears her melody echoing through the old concert hall—played perfectly by a girl he’s never met.
Soon, Ren and the other students are drawn into the “Symphony of Souls”, a ritual that binds their emotions to music. Every performance drains something from them—memories, feelings, or fragments of life itself. To graduate, they must each compose their Final Piece, but the truth is grim: only one can complete it, and the rest will vanish into their own unfinished songs.

Suddenly, the piano glowed brighter, notes forming visible threads in the air. A figure emerged—a ghostly manifestation of the melody itself, faintly resembling Airi.


Rei's voice quivered as she sang alongside it, blue aura intertwining with crimson and silver. The spirit of the melody responded, bowing to their combined power.


Nagi whispered, "It tests you. It will accept nothing but perfection."


Ren felt his entire body vibrate with the song. This was no longer music—it was living, sentient, demanding absolute precision. Every hesitation risked another student vanishing.
